In in v deviee I have found it beneficial to euiplolv two pl ungers4 forcoirtoiiiiing 111e Seal. r1 1111 outer plunger of tlie two is the lastto art. It 1111s upon its working end a eireular Shoulder which engagesthe upturned edge of the seal. Itaets to prevent 111e seal from freelyspreadingoutward as it is beinn1 turned over along the edge. andinstead. confines it within the circumferenceY of tlie shoulder, andcompels the superfluouS metal composing tbe ange of t-l1e seal to becrowded' down in the circular groove formed in the neck of 111e bottleto moet eileetively secure the seal in its compressed condition to itsseat in the bottle. I ain tlius enabled by a-Siinple downward movemento1' tbe )lunger to give to the upturned Yof this specification, Figure lis tlange or edge of the seal a formation much as iit a spreading toolexerting lateral pressure were used but without complicating my devicewith such additional means.

ln my device I hold the seal in place by means ot a split ring arrangedwithin a groove formed on the cylindrical tace of the seating plunger,the advantage of this construction will be more clearly seen as mydevice is explained in detail.

Referring to the drawings forming r a part .hn elevational Aview partlyin section of my de vice with the respective parts in their normalpositions. Fig. 2 a sectional elevational view of the plungcrs in theirlespective final positions upon a sealed bottle, and Fig. 3 is aperspective view of a prelcrred type of seal for use with my device.

For the purpose ot illustrating my invention I have preferred to showthedevice in its simplest form, that is to say, as a hand operatedmachine. My device, as is obvious.l may be used with other power fordriving it, such, for instance, as belt and pulley driven by foot7steam, etc. but in such instances additional reciprocating mechanismwould be needed.

A rigid stand or base l is provided for supporting the bottle 2prclnlratory to be` ing sealed. This stand may conveniently be a bracketsecured to a wall, post or other suitable place. To provide ayiclding'seatfor the bottle to overcome anj,T possible shock caused bythe descending plungers, the stand is provided with a rubber mat Ahollow post 4 firn'dy secured in upright position to the base 1. 'lhetop of this post may also be secured to the general support (not shown)as by a bracket Ii.

The post is for mounting the plungers upon. This is ln'e'lerablyaccmnplished by slidably mounting a sleeve t3 upon thelpost. Illhcsleeve is secuicd to the outer plunger by a web 7 and is cut awayproviding an opening S to t'acilitatr` the forming of a recessor chamber9 in the web. A pinion 1,0 is mounted within this chamber upon the shatt: 11. A rack 12 formed on the lace of post 4 is in mesh with thepinion'. wheel 1 3 is mounted on thc shaft 11 tor turning the pinionalthough other driving means may be employed it desired. By thismechanism the plunger as is obvious can he moved up and down to andtromy the bottle. Comi'icnsating mechanism is pro vided forcountcrbalancing the weight of the plungers. This preferably comprises aweight 14 of cylindrifzal forlnation placed within the hollow post. andconnected to the web of the plunger by a chain 15 extendingr over apulley 16 mounted on bracket 17 sccured at the top of the post.

The seal 18 shown in connection with my device is intended to representa type ol.

A Ah an dl seal formed of a disk of metal 1Q face-d by a smaller disk Q0of yielding materiall as cork. The part of the metal disk extendingbeyond the facing disk is upturned and provided with a plurality ofradial slits forn'iing thereby the serrated flange .1 composed of aplurality of independent members all radiating from the central bodypart. The bottle adapted for such a disk has formed within the neck acircular groove 22. The lower face of this groove forms a scat 23 forthe yielding disk Q0 and the groove itself forms a receptacle for theupwardly turned flange.

My method of sealing operates by simple pressure downward, to crilnp theflange within the groove of the bottle and around the outside thereof toform of each section an independent spring clip, so to speak, engagedwithin the groove and exerting its force-to assist in holding theyielding seal firmly upon its seat'. The strength of the combined clipsis sutiicient to form the sealed -ioint. The strength of any oneliowever is not so great but that it may be easily overcome by simplygrasping the overturned end thereof and forcing it back toward thecenter of the seal to free the crimped part from engagement with theshoulder 'formed by the groove in thc bottle. VNo tool is needed forthis as the sections of the flange are purposely made small enough tobe. disengaged by the fingers and when a sufficient number have beendisengaged the seal can be easily dislmlged `from the bottle. It. is notalways necessary nor expedient to leave all the .segments of the liangeyupon the seal, but advantage is gained by removing part oli themtherefrom, only leaving sutlcient to provide strength enough for thelocking joint. The seal shown hasl but four of these segments intact, It' y The construction and arrangement of the concentric plungers au` asfollows: The outer plunger (or receptacle) Z-l is preferably tubular inshape and opened at both ends. The lower cnd is formed with an upwardlyconverging interior rim 25 which is the lirst to contact with the bottle(if it bc much out of center) to movel it ncarcr its correct positionbelow the seal. 'llie rim is of sutlicient diameter, as bctorc remarlad,to pcrmit the neck of the bottle to pass entirely within it. lt has thcinternal flange 26 'formed thereon to all'ord a scat 'or tladjacent-plunger 27. This plunger is the next to contact with the bottlcand hasI at its lower end an upwardly convcrging interior rim QS, whichin normal position is a con tinuation of the rim ot' the t'zrst plunger.This rim is of a diameter to cngagc thcI outer edge ot the neck otthebottle. lt first completes thc ccntralizing ol the bottle and then holdsit lirmlv in that position during i. ...Mt .anar a...aaitmltmmlwmwmnm lal.

outer plunger' or receptacle.

the operation of the other plungers in seating and forming the seal.

The next plunger 29 is formed hollow and is closed at. the top by anenlarged head 30 of a sufficient size to slidably fit within the Thebody of the plunger is reduced in diameter to fit within the secondplunger 2T. The head il() is a suitable distance above the plunger 2T toaord a chamber for the helical spring 3l. The head rests in normalposition against one or more lugs 32 formed on the plunger :24. Thesecond and third plungers are placed in their respective positionswithin the first plunger from the top thereof and to permit the secondplunger to pass the lugs 32 grooves are formed therein. The firstplungeris preferably externally threaded to receive the correspondinglyinternally threaded cap 34 provided with a head adapted to receive awrench for turning it. lVithin the chamber formed between the cap andhead 30 of the third plunger is a helical spring 3G. This spring is ofsufcient strength to withstand the pressure of the other springs as theyare con'ipressed during the sealing operation. The lugs 32 which Iprovide for seating the Vplunger 2t) in norma-l position enable thespring 8G to be normally under compression without; affecting therelative positions of the plungers or the tensions in the other springs,but providing the necessary resistance to complete the sealing opeation. The working end 37 of this plunger has the shoulder 88 formedtherein for receiving the upt-urned edge of the seal flange and to conneit as has already been described. This plunger is the 'last to actand isaccordingly the highest in position.

The next plunger 39 is mounted within the plunger Qt) and has a workinglower end normally below the end of that plunger. lt is the first tobegin forming the flange of the seal. The working end of this plunger isformed with an upwardly diverging face.

This provides pressure upon the edge of the flange to force it downwardin the groove of the bottle and aty the same time to cause it to spreadoutward. The plunger is secured in proper normal position preferably bya pin 40 extending through the stein of the plunger and having its endsprojecting in the slots 41-41 formed in the plunger 2S) to permit therequired relative motion. Above the plunger 39 is a spring 42 foraffording the necessary resistance. The lower end of the plunger ispreferably enlarged forming a `shoulder 43. This ts within a.corresponding enlargement formed in the plunger 29 affording a seat 44for the plunger 39 which together with the pin 40 and slots 4l limit therelative movement of the two plungers.

The plunger 39 has its lower end formed hollow for a suitable distance`upwardly to -the plunger l5 to restrict its movement iro plunger 3f).The plunger 45 is retained in .normal position by the screw -lt passedthrough the plunger and screwed tight into the plunger 3f). A spring 4Tis mounted on the` screw behind the plunger 45 to provide the requiredresistance. The plunger 4I) is for receiving the seal and for carryingit down upon its seat in the bottle and for compressing it there. Thisplunger is formed with a groove 48 in which is seated a split ring 49.This ring projects normally beyond the face of the plunger, and engagesin spring-pressed engagement with a seal when slipped over it. This ringhas the advantage that it securely holds the seal in place upon theplunger until it is well upon its scat in the bottle. This insures apositive centralizing of the seal on its seat. My manner of holding theseal7 as before remarked, holds it firmly to the seating plunger untilwell down upon the bottle scat. The serrated flange on the seal ispreferably formed slightly flaring and this malies it admirably adaptedto be slipped over my splity ring.
